	HLT_DoubleEle8_CaloIdM_TrackIdM_Mass8_DZ_PFHT350: electron leg (barrel) The efficiency of the electron leg of a High-Level Trigger (HLT) algorithm that requires two well-identified electrons with a transverse momentum pT greater than 8 GeV, an invariant mass greater than 8 GeV, and a hadronic transverse energy HT greater than 350 GeV. HT is defined as the scalar pT sum of all reconstructed jets that have pT > 30 GeV and abs(eta) < 2.5. Tight conditions are applied on the transverse and longitudinal shower shapes of the electrons. The algorithm also requires a difference of longitudinal impact parameter (with respect to the leading primary vertex) DZ < 0.2 cm. The Level-1 (L1) trigger condition requires two electromagnetic objects with a transverse energy greater than 8 GeV and HT > 300 GeV. The black points, and the associated y axis on the left, correspond to the efficiency of the electron pT , identification, and DZ criteria. It is calculated using a tag-and-probe method with Z in ee events recorded by two trigger algorithms: the first one requires an isolated electron with pT > 35 GeV ; the second one requires an electron with pT > 15 GeV and HT > 450 GeV. The efficiency is shown as a function of the offline electron pT , for electrons reconstructed in the central part of the electromagnetic calorimeter (abs(eta)< 1.479). The HLT dielectron mass criterion has been studied separately, and it is shown to be fully efficient in the phase space region of interest. The numerator (filled histogram) and denominator (dashed line) entering the efficiency calculation are also shown (y axis on the right). Their last bin includes the overflow entries. The rate of this HLT algorithm is 2 Hz for an instantaneous luminosity of 1.8X10³⁴ Hz cm-2 and an average pileup (secondary pp collisions occuring in an LHC proton bunch crossing) of 50.

The calculation of both MET and MHT excludes the contribution from all muons in the event. HT is defined as the scalar pT sum of all reconstructed jets that have pT > 30 GeV and abs(eta) < 2.5. The Level 1 condition requires at least 100 or 110 GeV of MET and at least 60 GeV of HT. At Level 1, jets (MET) are reconstructed (is calculated) based on the calorimeter information only and do not (does not) include muons. The black points, and the associated y axis on the left, correspond to the efficiency. It is calculated using events recorded by a trigger requiring an isolated high pT muon (> 27 GeV). The selected events are also required to contain exactly one offline muon, no offline electron and have HT > 100 GeV. The efficiency is shown as a function of the offline MET, also excluding muons from the energy sum. The numerator (filled histogram) and denominator (dashed line) entering the efficiency calculation are also shown (y axis on the right). Their last bin includes the overflow entries. The rate of this HLT algorithm is 23 Hz for an instantaneous luminosity of 1.8X10³⁴ Hz cm-2 and an average pileup (secondary pp collisions occuring in an LHC proton bunch crossing) of 50.

HLT_PFMETNoMu120_PFMHTNoMu120_IDTight_PFHT60
The efficiency of a High-Level Trigger (HLT) algorithm that requires a missing transverse energy MET greater than 120 GeV, a missing transverse hadronic energy MHT greater than 120 GeV, and a transverse hadronic energy HT greater than 60 GeV. MET is defined as the amplitude of the negative vector sum of the transverse momentum pT of all particle candidates. MHT is defined as the amplitude of the negative vector sum of the transverse momentum pT of all jets with pT > 20 GeV and abs(eta) < 5 that pass tight identification criteria based on their components and charged/neutral hadronic/electromagnetic energy fractions. The calculation of both MET and MHT excludes the contribution from all muons in the event. HT is defined as the scalar pT sum of all reconstructed jets that have pT > 30 GeV and abs(eta) < 2.5.
